Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, fuel pressure gauge, multimeter.
Disconnect the battery to ensure safety before starting any electrical work.

2. Clean the Throttle Body

Remove the air intake duct from the throttle body.
Use throttle body cleaner and a soft brush to clean the throttle plate and surrounding area.
Reattach the duct securely and reconnect the battery.

3. Inspect and Replace Spark Plugs (if necessary)

Remove the ignition coil covers using a socket set.
Disconnect the ignition coils and remove them from the spark plugs.
Replace spark plugs with OEM specifications, ensuring proper torque (typically around 13 lb-ft).
Reinstall ignition coils and covers.

4. Check Fuel Pressure

Connect a fuel pressure gauge to the fuel rail.
Turn the ignition to the ON position without starting the engine and check the pressure reading (should be within manufacturer specifications).
If pressure is low, inspect the fuel pump and fuel filter for issues.

5. Inspect Transmission Fluid

Locate the transmission dipstick and remove it.
Check fluid level; if low, add the appropriate type of transmission fluid (consult owner’s manual for specifications).
If fluid is dark or has a burnt smell, consider a fluid exchange.
